STOVE-PIPE ANCHOR.

SPECIFICATION forming part of Letters Patent No. 344,332, dated June 22, 1886.

Application filed August 13, 1885.

To all whom, it may concern.-

Be it known that 1, CHARLES BIRD TUCK- FIELD, of Salt Lake City, in the county of Salt Lake and Territory of Utah, have invented a new and Improved Stove-Pipe Anchor, of which the following is a full, clear, and exact description.

The object of my invention is to provide an attachment whereby stove-pipes may be secured and held in proper position within the opening leading to the fiue, and whereby the upper joints will be securelylocked together; and to this end my invention consists of two adj ustably-connected rods which carry clamping attachments, as will be hereinafter de scribed, and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

igure 1 is a side view of my attachment, representing the same in position for use, the chimney and stove-pipe being shown in section to disclose the position of the parts. Fig. 2 is an enlarged side view of the attachment, parts being broken away. Fig. 3 is asectional view on line w m of Fig. 2. and Fig. 4 is a sectional view on line y y of the same figure.

Referring now to the construction of the attachment, which is best seen in Fig. 2, a and I) are two bars or rods, of iron or other proper metal, which are preferably rectangular in cross-section. The rod a is pointed, as shown at a, while one end of the rod b is threaded, as shown at d, for engagement with a thumb nut, e. The two bars a and b are adjustably united by the clamp f, which consists of a strip of cast, wrought, or malleable iron, bent or cast to U form and provided with openings g 9, one in each leg of the clamp, and through these openings the bars a b are passed.

In the top of the clampf there is athreaded hole, with which the angular set-screw h engages, so that as it is turned down its point will bear upon the uppermost of the two bars a and b, and thus securely clamp the two together. The bar a carries a clamp, k, which is substantially the same as the clamp f, except that one leg, as Z, is elongated, and its lower end, i, is bent forward toward the point Serial No. 174.278. (No model.)

0 of the said bar a. The clamp It carries an angular set-screw, n, by which it is secured to the bar a in such position as the circumstances of the case require.

To apply the attachment, :1. small hole about half an inch deep is made in the back wall of the flue, about in line with or a little above the bottom of the opening in the chimney A, within which the longitudinal sectionm of the stove-pipe is inserted, and the point 0 is placed in the hole so made, after which the clamp is is moved forward until the leg Z rests against the front wall of the flue, in which position the clamp is secured to the bar a, as shown in Fig. 1. As the end t' of the leg Z iscarried in toward the point a, the attachment may easily be removed from the chimney by simply raising its outer end, and may at any time be replaced by first inserting the point 0 in the hole formed in the back wall of the fine. The length of the pipe m and the elbowp (which parts may be integral, as shown in the drawings, or separate and united in the usual manner) having been determined, the rods a and b are adjusted and clamped together by the set-screw it, so that when fitted within the pipe the threaded end d of the rod 1) will project beyond the elbow p. The elbow p is punctured with a square hole, so that the threaded end d of the bar 1) maybe passed through from the inside to the outside of the pipe. After the attachment has been properly adjusted it is placed so that the point 0 will enter the hole formed in the back wall of the flue and the leg 1 rest against the front wall. The pipe in is then inserted in the opening leading to the flue, the attachment being within the pipe, which is shoved back until its inner end abuts against the leg I of the clamp It. When the parts are in the position described, the threaded end of the bar I) will project out through the opening formed in the elbowp in position to engage with the thumbnut e, which is turned back against the outside of the elbow, as shown in Fig. 1, thus locking the parts together.

This attachment is cheap, durable, and ef fective, and does not detract from the appearauce of the pipe, as it is covered thereby. The square hole in the elbow fits the square bar b, thus keeping the leglin a vertical position against the wall of the flue, so that the hori- 2; The combination, with the rod a, pointed to zontal length of pipe and the elbow will be at c, and carryinga clamp, 70, formed with aleg, held in place when the vertical pipe is re- Z, of the rod b, clamp f, and thumb-nut 6, submoved.
